METHOD OF PARAMETRIC SYNTHESIS OF DIGITAL CONTROL SYSTEMS BASED ON EXTENDED AMPLITUDE-PHASE CHARACTERISTICS
This paper describes the solution on the problem of calculation parameters for PI-controller, which provides minimum value for quadratic evaluation in desired level of oscillation. PIcontroller parameters are found on D-partition graphic with single-level searching. D-partition graphic is obtained using extended amplitude and phase characteristics on open-loop system.
Keywords: digital control systems, parametric synthesis, amplitude and phase characteristics, D-partition, transition process.
